SUMMARY

Ontologist and Semantic Architect with 10+ years building RDF/OWL ontologies, knowledge graphs,

and semantic metadata systems for complex enterprise environments. Deep hands-on experience with

W3C standards (SPARQL, OWL, SKOS, RDFS), graph databases (GraphDB Ontotext, Neo4j), and

enterprise taxonomy management platforms (TOMS). Track record of enabling cross-system data

integration, semantic search, and personalization at scale across siloed enterprise content ecosystems.

Strong foundation in NLP-driven metadata extraction, information architecture, and content

management strategy. Proven ability to translate ambiguous business requirements into structured,

intuitive ontologies that drive analytics, discovery, and customer experience outcomes.

PROFESSIONAL EXPERINCE

Ontology Engineer / Knowledge Graph Specialist

- Designed and maintained enterprise RDF/OWL ontologies for an AI product suite,

enabling semantic interoperability across computer vision, NLP, and agentic AI

modules.

- Built a knowledge graph layer using GraphDB Ontotext for a large-scale multi-

camera vision system,



mapping entity relationships across face recognition, inventory,

and warehouse management domains.

- Developed SPARQL-based analytics pipelines for cross-domain querying, reducing

prospect research time from hours to under two minutes in a presales orchestration

tool.

- Led semantic metadata extraction using spaCy and custom NER models to auto-tag

enterprise documents, improving content discoverability by 40%.• Created taxonomy structures and controlled vocabularies for a government AI

services empanelment initiative, ensuring standards compliance across consortium

deliverables.

- Applied SHACL validation constraints to enforce ontology quality and consistency

across distributed development teams.

- Mapped business requirements to ontological models for client-facing AI solutions

across retail, education, and quick-commerce verticals, translating ambiguous

stakeholder needs into structured semantic schemas.

Senior Developer / Semantic Integration Lead

- Led semantic layer design for a consumer super-app, building OWL ontologies to

unify product catalogs, user profiles, and transaction data across multiple brands

within a conglomerate.

- Implemented entity resolution and semantic deduplication using graph-based

matching algorithms, improving data consistency across distributed databases and

internal APIs.

- Developed SPARQL query interfaces for business intelligence dashboards, enabling

cross-brand analytics and personalization at scale.





- Built and deployed containerized semantic microservices (Docker/AWS ECS) for

real-time content classification and recommendation.

- Integrated LLM-based agentic workflows with knowledge graph backends for

intelligent customer support and internal tooling.

- Designed RDF-based metadata schemas for progressive web app content, enabling

semantic search and discovery across product categories.

Data Engineer / Ontology Specialist

- Built enterprise taxonomies and classification schemas for ETL data pipelines,

ensuring semantic consistency in data warehousing workflows.

- Developed RDF/SKOS vocabularies for content tagging in full-stack applications,

enabling faceted search and content discovery.

- Created ontology-driven data validation frameworks using Python, reducing data

quality issues by 35% in high-volume ingestion pipelines.

- Worked with enterprise vocabulary management tooling to maintain controlled

vocabularies across distributed teams.

- Contributed to data workbench backend optimizations, integrating semantic metadata

layers for cross-team data collaboration.

- Containerized semantic services and deployed on Kubernetes clusters for scalable

graph query processing.

Developer / Content Taxonomy Contributor

- Developed content classification taxonomies for video ad targeting, enabling

semantic audience segmentation using industry-standard video ad metadata formats.

- Built automated tagging pipelines using NLP techniques to extract semantic metadata

from video content for ad personalization.• Configured CI/CD pipelines and cloud-based infrastructure for content delivery with

semantic content routing.
